To (ZZZ whom 2'2. may concern Be it known that I, JAMES'H- L. EAGER, a citizen of the United States, residing at New York, in the county of Kings, State of New York, have made a certain new and useful Invention in Syringes, of which the following is a specification.

The invention relates to syringes, and

i more particularly to that class known as water bag syringes and in which a pressure seat is used which rests upon the bag, the weight of the person using the syringe causing the water or other cleansing fluid to be forced from such bag and through an injection nozzle to the part to be treated.

The object of the invention is to provide a syringe of the class described including an improved type of pressure seat and fluid control device.

Further objects of the invention will appear more fully hereinafter.

The invention consists substantially in the construction, combination, location and relative arrangement of parts, all as will be more fully hereinafter set forth, as shown by the accompanying drawing, and finally pointed out in the appended claims.

v any suitable material Referring to the drawing:-

Figure 1 is a top plan view of a syringe ber cloth having a screw threaded filling opening 6. I provide a pressure seat 7 of preferably of rubber or rubber cloth extending substantially over the entire surface of the bag 5. The upper surface of the bag 5 is provided with an opening 8 formed with upwardly extending walls 9 provided with internal screw threads as shown best in Fig. 3. A nozzle 10 of any desired material, preferably of some soft composition such as rubber, screws into the opening 8 or the opening 6. The pressure seat 7 is split as at 11, and is providedwith Specification of Letters Pam.

a flared portion 12 which embraces the neck 9. Secured to edgesof the pressure seat 7 and pivotally secured to each other as at 13 are two pressure tongs 14, 15, which when pressed tightly together securely pinches the walls 8 together and prevents further flow of the fluid from the bag through the nozzle, as shown best in Fig. A. The tongs may be held together in their pinched position in any suitable manner, as, for example, by the well known form of latch device 20 which is pivotally connected to the tong 15 and adapted to slip over the tong 14:.

It is obvious that by the mere manipulation of the tongs 14: and 15, the fluid from the bag can be readily controlled.

It is obvious that when the syringe is adjusted for use, the weight of the body of the user on the pressure seat, will cause the water or fluid contained in the bagto flow through the nozzle to the part or parts to be treated.

Having now set forth the object and nature of my invention, and having shown and described a structure embodying the principles thereof, what I claim as new and useful and of my own invention and desire to secure by Letters Patent, is

1. A syringe comprising a water bag pro vided with a neck, a pressure seat adapted to rest on said bag, and to surround said neck, and means carried by said pressure seat for pinching said neck to control the supply of fluid from said bag through said nec 2. A syringe comprising a water bag provided with a neck adapted to receive a nozzle therein, a pressure seat adapted to rest on said bag and to surround said neck, and

means carried by said pressure seat for pinching said neck to control the supply of fluid from said bag to said nozzle.

8. A syringe comprising a water bag provided with a'neck adapted to receive a nozzle therein, a pressure seat adapted to rest upon said bag and split a substantial dis tance through its center, to allow the same to surround said neck, and tongs carried by the respective sides of the split pressure seat and pivotally connected to each other, for controlling the supply of fluid from said bag to said nozzle.

4:. A syringe comprising a water bag provided with a neck adapted to receive a nozzle therein, a pressure seat adapted to rest upon said bag and split a substantial distween said bag and said nozzle, and means tance through its center, to allow the same carried by said tongs for locking the same to surround said neck, and tongs carried by in their closed position. 10 the respective sides of the split pressure seat testimony" whereof I have hereunto 5 and pivotally connected to each other, and set my hand on this 27th day of June, A. D.
